So far, mine is multiplying golf balls, but with more practice in front of the mirror, I shall master it soon. I find it satisfying to work through the difficulties that some of these tricks present. It is wery worthwhile once they are successfully executed!
Hey, I was 15 when I learned the multiplying Golf Balls, and I have only mastered the simplest routine in which the balls multiply from one to four... while at the #2 i keep taking away one and it comes back... and then one vanishes and appears in my coat breast pocket or shirt pocket. I finish by reducing the number from 4 to one by tossing them into the audience where they vanish, one at a time. The final ball I toss to the air three times and on the third toss it vanishes. I don't remember whose basic routine this is. I have continued to perform this routine with minor changes for 61 years. Now I do the same routine with bubbles (glass). Of course if you work at it you can do even more difficult effects with the billiard balls. Keep practicing. Do you enjoy performing this for a live audience?
